It'll take a little while (up to 48 hours) for the change to propagate, but once it has the 'naked' domain will be directed to your "www." subdomain.

Note

SSL certificates are applied to a subdomain (e.g. www.mysite.com),rather than a naked domain (e.g. mysite.com). If you set up a naked domain redirect, this means http://mysite.com will redirect to http://www.mysite.com, but https://mysite.com will not redirect to https://www.mysite.com.

Why this Process is Important

We insist you create a CNAME record for your custom domain that points to unbouncepages.com instead of an A record that points to a particular server's IP address. The reason we do this is that we continually upgrade our infrastructure, adding servers in multiple distributed locations to serve up pages faster world-wide, and if you pointed your custom domain at one particular IP address, your pages would break as we add servers. (And that would be bad.)

CNAMEs can take up to 48 hours to propagate. Once it's ready, you can ensure your pages are published where you want by making sure your domain is added to Unbounce and your landing pages are pointing to your custom domain.
